No full textIn order to understand the promoting effect of V compd. on Rh catalysts in synthesis gas conversion, changes in reaction rates of elementary steps and the surface concn. of intermediates have been monitored. V promotion enhances the rate of CO dissocn. which is the most important effect. Reactive surface carbon is stabilized by V which results in a slightly decreased reactivity in methane formation. Transient expts. using isotopes and GCMS detection show that CO insertion is not promoted by V. The hydrogenation of ethanal to ethanol is enhanced by V while the desorption rate of ethanal is decrease
